NKK Switches UB2 Low-Profile Pushbutton Switches
NKK Switches UB2 Low-Profile Pushbutton Switches come in a wide selection of illumination effects, achieved with single and bicolor, 1- or 6-element LEDs in flat, beveled, or sculptured caps. The switches' combination of PCB mountability and a short body allows for compact applications. These pushbutton switches have a snap-acting contact mechanism that provides sensitive actuation with audible feedback. The switches have epoxy-sealed terminals to lock out flux, solvents, and other contaminants. UB2 pushbutton switches find applications in audio/visual control consoles, patient monitors, and diagnostic equipment.
